CVE-2022-48792

In the Linux kernel, the following vulnerability has been resolved: scsi: pm8001: Fix use-after-free for aborted SSP/STP sas_task Currently a use-after-free may occur if a sas_task is aborted by the upper layer before we handle the I/O completion in mpi_ssp_completion() or mpi_sata_completion(). In this case, the following are the two steps in handling those I/O completions: - Call complete() to inform the upper layer handler of completion of the I/O. - Release driver resources associated with the sas_task in pm8001_ccb_task_free() call. When complete() is called, the upper layer may free the sas_task. As such, we should not touch the associated sas_task afterwards, but we do so in the pm8001_ccb_task_free() call. Fix by swapping the complete() and pm8001_ccb_task_free() calls ordering.

Cuando se llama a complete(), la capa superior puede liberar sas_task. Como tal, no debemos tocar el sas_task asociado despu\u00e9s, pero lo hacemos en la llamada pm8001_ccb_task_free().
